Risk Management for Electronic Banking and Electronic Money Activities
1. Introduction
Electronic payment media are likely to figure importantly in the development of
electronic commerce, and retail electronic banking services and products, including electronic
money, could provide significant new opportunities for banks. Electronic banking may allow
banks to expand their markets for traditional deposit-taking and credit extension activities,
and to offer new products and services or strengthen their competitive position in offering
existing payment services. In addition, electronic banking could reduce operating costs for
banks.
More broadly, the continued development of electronic banking and electronic
money may contribute to improving the efficiency of the banking and payment system and to
reducing the cost of retail transactions nationally and internationally. This could potentially
result in gains in productivity and economic welfare. Consumers and merchants may be able
to increase the efficiency, with which they make and receive payments, and enjoy greater
convenience. Electronic banking may also increase access to the financial system for
consumers who have previously found access limited.
The scope of this report is necessarily restricted in two respects. First, it deals with
the risk management of electronic banking and electronic money activities from a banking
supervisory perspective only and does not, for example, address the monetary consequences.
Second, while many of the risks described in the report apply both to bank and non-bank
issuers and providers, this report addresses banks only.
1.1. Purpose and organisation
The development and use of electronic money and some forms of electronic
banking are still in their early stages. Given the degree of uncertainty about future
technological and market developments in electronic banking and electronic money, it is
important that supervisory authorities avoid policies that hamper useful innovation and
experimentation. At the same time, the Basle Committee recognises that along with the
benefits, electronic banking and electronic money activities carry risks for banking
organisations, and these risks must be balanced against the benefits.
The purpose of this document is to provide considerations for supervisory
authorities and banking organisations as they develop methods for identifying, assessing,
managing and controlling the risks associated with electronic banking and electronic money.

The Basle Committee regards the document as an initial step in an ongoing review and
discussion of supervisory issues and responses related to technological advances in electronic
retail products and services.
The Basle Committee is distributing this document to supervisors worldwide with
the expectation that it will facilitate development of appropriate supervisory approaches to the
management of risks in electronic banking and electronic money activities. Supervisors may
wish to circulate the document to the institutions under their jurisdiction.
The discussion is general in nature because the technology for electronic banking
and electronic money is changing rapidly, and products and services in the future may be very
different from those available today. At this relatively early stage in the development of some
electronic banking and electronic money activities, many aspects of risks are neither fully
discernible nor readily measurable. A premature regulatory approach would run the risk of
stifling innovation and creativity in these areas. Therefore, supervisors should encourage
banks to develop a risk management process rigorous and comprehensive enough to deal with
known material risks, and flexible enough to accommodate changes in the type and intensity
of material risks associated with their electronic banking and electronic money activities. The
risk management process can be effective only if it is constantly evolving.
The remainder of this document is organised as follows. The next section of the
Introduction presents definitions of electronic banking and electronic money, and refers to key
roles banks can play as participants in electronic money activities. Section II identifies risks
that banks may face in electronic banking and electronic money. The identification and
analysis of risks does not aim to be exhaustive; rather, the discussion is intended to be
illustrative of the types of problems banks may face. Among these, analysis suggests that
operational, reputational, and legal risk may be more likely to arise.1
As the development of electronic banking and electronic money progresses,
interaction between banks and their customers across national boundaries is likely to increase.
Such relationships may raise different issues and risks for banks and for supervisors. In light
of this, Section II includes a discussion of cross border risks.
Based on the identification and analysis of risks, Section III outlines the major
steps in a risk management process for banks engaging in electronic banking and electronic
1 Banks are also likely to face risks that can affect the value of their shareholders’ interest. For example,
faced with a choice between competing new technologies, bank management risks choosing one whichdoes not become widespread and hence may not be successful, or it may choose one which does not fitwell with other products and services. As with any business decision management takes, risks to financialsuccess posed by electronic banking and electronic money are of central concern to it and to owners.However, because supervisory authorities are charged with protecting the safety and soundness of thebanking system, but not with ensuring bank profitability, such "shareholder value" issues are not of directconcern to supervisors, unless the viability of an institution is threatened. Therefore, in general, thedocument does not discuss this perspective on electronic money and electronic banking risks.

money activities. The process has three main steps: assessing risks, implementing measures to
control risk exposures, and monitoring risks.
1.2. Definitions of electronic banking and electronic money
1.2.1 Electronic banking refers to the provision of retail and small value banking
products and services through electronic channels.2 Such products and services can include
deposit-taking, lending, account management, the provision of financial advice, electronic bill
payment, and the provision of other electronic payment products and services such as
electronic money (defined separately, below).
Two fundamental aspects of electronic banking are the nature of the delivery
channels through which activities are pursued, and the means for customers to gain access to
those channels. Common delivery channels include "closed" and "open" networks. "Closed
networks" restrict access to participants (financial institutions, consumers, merchants, and
third party service providers) bound by agreements on the terms of membership. "Open
networks" have no such membership requirements. Currently, widely used access devices
through which electronic banking products and services can be provided to customers include
point of sale terminals, automatic teller machines, telephones, personal computers, smart
cards and other devices.
1.2.2 Electronic money refers to "stored value" or prepaid payment mechanisms
for executing payments via point of sale terminals, direct transfers between two devices, or
over open computer networks such as the Internet.3 Stored value products include "hardware"
or "card-based" mechanisms (also called "electronic purses"), and "software" or
"network-based" mechanisms (also called "digital cash"). Stored value cards can be
2 This document focuses on retail electronic banking and electronic payment services. Large-value
electronic payments and other wholesale banking services delivered electronically are outside the scope ofthe present discussion.
3 Several official bodies have each issued their own definition of electronic money. As pointed out in arecent Group of Ten report on electronic money, a precise definition of electronic money is difficult toprovide, in part because technological innovations continue to blur distinctions between forms of prepaidelectronic mechanisms. (See Electronic Money: Consumer protection, law enforcement, supervisory andcross-border issues, Group of Ten, April 1997, for a list of such studies.) The current document drawsfrom both the Group of Ten report and Security of Electronic Money, Bank for International Settlements,August 1996, in establishing a definition of electronic money. The latter report explains distinctions in thetechnical representation of money on stored-value products. In particular, "balanced-based" products aredevices which manipulate a numeric ledger, such that transactions are performed as debits or credits to abalance; and "note-based" products which perform transactions by transferring the appropriate amount ofelectronic "notes" (also called "coins" or "tokens"), which are of a fixed denomination, from one device toanother. Debit cards and credit cards are retail electronic payment mechanisms, but are not considered tobe electronic money because they are not prepaid mechanisms.

"single-purpose" or "multi-purpose".4 Single-purpose cards (e.g., telephone cards) are used to
purchase one type of good or service, or products from one vendor; multi-purpose cards can
be used for a variety of purchases from several vendors.5
Banks may participate in electronic money schemes as issuers, but they may also
perform other functions. Those include distributing electronic money issued by other entities;
redeeming the proceeds of electronic money transactions for merchants; handling the
processing, clearing, and settlement of electronic money transactions; and maintaining records
of transactions.
2. Identification and analysis of risks
Because of rapid changes in information technology, no list of risks can be
exhaustive. The intention in this document is to describe a broad, representative set of risks as
a basis for designing general guidance for risk management. Specific risks facing banks
engaged in electronic banking and electronic money activities can be grouped according to
risk categories discussed in other Basle Committee risk management documents and, in this
sense, the risks are not new.6 Categorising risks in this manner can be helpful in
systematically identifying risks in a banking organisation. The Annex presents examples of
specific risks and problems banks may face in electronic banking and electronic money
activities grouped into risk categories.
While the basic types of risks generated by electronic banking and electronic
money are not new, the specific ways in which some of the risks arise, as well as the
magnitude of their impact on banks, may be new for banks and supervisors. Some of the risks
and problems banks may face apply both to electronic money and electronic banking
activities. However, there are likely to be differences in the degree to which a particular risk is
applicable across different electronic money and electronic banking activities.
4 Stored value cards may be characterised by the use of a magnetic stripe or a computer chip embedded in
the card. A plastic card with an embedded computer chip (known as a "smart card") may perform storedvalue applications, in addition to other functions such as debit and credit applications.
5 Increasingly, the terms multi-purpose or multi-function are also used to convey the idea that the card ordevice can function as several types of payment instrument (e.g. credit card, debit card, stored value card),and/or that the card can be used for purposes besides financial transactions (e.g. identification card,repository of personal medical information). The lack of standardisation of terminology is perhaps areflection of rapid technological innovations.
6 See, e.g., Risk Management Guidelines for Derivatives, Basle Committee on Banking Supervision, July1994, and Core Principles for Effective Banking Supervision, Basle Committee on Banking Supervision,September 1997. The latter document includes a basic discussion of eight risk categories: credit risk,country and transfer risk, market risk, interest rate risk, liquidity risk, operational risk, legal risk andreputational risk. Payment Systems in the Group of Ten Countries, Bank for International Settlements,December 1993, includes definitions of risks in banking and payment systems.

At this stage, it would appear that operational risk, reputational risk, and legal risk
may be the most important risk categories for most electronic banking and electronic money
activities, especially for diversified international banks, and the next three subsections discuss
specific manifestations of these types of risks. Some of the specific problems cut across risk
categories. For example, a breach of security allowing unauthorised access to customer
information can be classified as an operational risk, but such an event also exposes the bank to
legal risk and reputational risk. Even though these different types of risks may result from a
single problem, appropriate risk management may require several remedies to address each of
these different risks. Other risks may also be important for some forms of electronic banking
and electronic money activities, and these are discussed thereafter. Possible cross border risks
are also discussed.
2.1. Operational risk
Operational risk arises from the potential for loss due to significant deficiencies in
system reliability or integrity. Security considerations are paramount, as banks may be subject
to external or internal attacks on their systems or products. Operational risk can also arise
from customer misuse, and from inadequately designed or implemented electronic banking
and electronic money systems. Many of the specific possible manifestations of these risks
apply to both electronic banking and electronic money.
2.1.1 Security risks
Operational risk arises with respect to the controls over access to a bank’s critical
accounting and risk management systems, information that it communicates with other parties
and, in the case of electronic money, measures the bank uses to deter and detect
counterfeiting. Controlling access to bank systems has become increasingly complex due to
expanded computer capabilities, geographical dispersal of access points, and the use of
various communications paths, including public networks such as the Internet. It is important
to note that with electronic money, a breach of security could result in fraudulently created
liabilities of the bank. For other forms of electronic banking, unauthorised access could lead
to direct losses, added liabilities to customers or other problems.
A variety of specific access and authentication problems could occur. For
example, inadequate controls could result in a successful attack by hackers operating via the
Internet, who could access, retrieve, and use confidential customer information. In the absence
of adequate controls, an outside third party could access a bank’s computer system and inject
a virus into it.
In addition to external attacks on electronic money and electronic banking
systems, banks are exposed to operational risk with respect to employee fraud: employees

could surreptitiously acquire authentication data in order to access customer accounts, or steal
stored value cards. Inadvertent errors by employees may also compromise a bank’s systems.
Of direct concern to supervisory authorities is the risk of criminals counterfeiting
electronic money, which is heightened if banks fail to incorporate adequate measures to detect
and deter counterfeiting. A bank faces operational risk from counterfeiting, as it may be liable
for the amount of the falsified electronic money balance. In addition, there may be costs
associated with repairing a compromised system.
2.1.2 Systems design, implementation, and maintenance
A bank faces the risk that the systems it chooses are not well designed or
implemented. For example, a bank is exposed to the risk of an interruption or slow-down of
its existing systems if the electronic banking or electronic money system it chooses is not
compatible with user requirements.
Many banks are likely to rely on outside service providers and external experts to
implement, operate, and support portions of their electronic money and electronic banking
activities. Such reliance may be desirable because it allows a bank to outsource aspects of the
provision of electronic banking and electronic money activities that it cannot provide
economically itself. However, reliance on outsourcing exposes a bank to operational risks.
Service providers may not have the requisite expertise to deliver services expected by the
bank, or may fail to update their technology in a timely manner. A service provider’s
operations could be interrupted due to system breakdowns or financial difficulties,
jeopardising a bank’s ability to deliver products or services.
The rapid pace of change that characterises information technology presents banks
with the risk of systems obsolescence. For example, computer software that facilitates the use
of electronic banking and electronic money products by customers will require updating, but
channels for distributing software updates pose risks for banks in that criminal or malicious
individuals could intercept and modify the software. In addition, rapid technological change
can mean that staff may fail to understand fully the nature of new technology employed by the
bank. This could result in operational problems with new or updated systems.
2.1.3 Customer misuse of products and services
As with traditional banking services, customer misuse, both intentional and
inadvertent, is another source of operational risk. Risk may be heightened where a bank does
not adequately educate its customers about security precautions. In addition, in the absence of
adequate measures to verify transactions, customers may be able to repudiate transactions they
previously authorised, inflicting financial losses on the bank. Customers using personal
information (e.g., authentication information, credit card numbers or bank account numbers)
in a non-secure electronic transmission could allow criminals to gain access to customer

- 7 -
accounts. Subsequently, the bank may incur financial losses because of transactions customers
did not authorise. Money laundering may be another source of concern, as pointed out in the
Group of Ten, April 1997, report: Electronic Money: Consumer Protection, Law
Enforcement, Supervisory and Cross-Border Issues.
2.2. Reputational risk
Reputational risk is the risk of significant negative public opinion that results in a
critical loss of funding or customers. Reputational risk may involve actions that create a
lasting negative public image of overall bank operations, such that the bank’s ability to
establish and maintain customer relationships is significantly impaired. Reputational risk may
also arise if actions by the bank cause a major loss of public confidence in the bank’s ability to
perform functions critical to its continued operation. Reputational risk can arise in response to
actions a bank itself takes, or in response to actions of third parties. Increased reputational risk
can be a direct corollary of heightened risk exposure, or problems, in other risk categories,
particularly operational risk.
Reputational risk may arise when systems or products do not work as expected
and cause widespread negative public reaction. A significant breach of security, whether as a
result of external or internal attacks on a bank’s system, can undermine public confidence in a
bank. Reputational risk may also arise in cases where customers experience problems with a
service but have not been given adequate information about product use and problem
resolution procedures.
Mistakes, malfeasance, and fraud by third parties may also expose a bank to
reputational risk. Reputational risk can arise from significant problems with communications
networks that impair customers’ access to their funds or account information, particularly if
there are no alternative means of account access. Substantial losses caused by mistakes of
another institution offering the same, or similar, electronic banking or electronic money
products or service may cause a bank’s customers to view its products or service with
suspicion, even if the bank itself did not face the same problems. Reputational risk may also
arise from targeted attacks on a bank. For example, a hacker penetrating a bank’s web site
may alter it to intentionally spread inaccurate information about the bank or its products.
Reputational risk may not only be significant for a single bank but also for the
banking system as a whole. If, for instance, a globally active bank experienced important
reputational damage concerning its electronic banking or electronic money business, the
security of other banks' systems may also be called into question. Under extreme
circumstances, such a situation might lead to systemic disruptions in the banking system as a
whole.

2.3. Legal risk
Legal risk arises from violations of, or non-conformance with laws, rules,
regulations, or prescribed practices, or when the legal rights and obligations of parties to a
transaction are not well established. Given the relatively new nature of many retail electronic
banking and electronic money activities, rights and obligations of parties to such transactions
are, in some cases, uncertain. For example, application of some consumer protection rules to
electronic banking and electronic money activities in some countries may not be clear. In
addition, legal risk may arise from uncertainty about the validity of some agreements formed
via electronic media.
Electronic money schemes may be attractive to money launderers if the systems
offer liberal balance and transaction limits, and provide for limited auditability of transactions.
Application of money laundering rules may be inappropriate for some forms of electronic
payments. Because electronic banking can be conducted remotely, banks may face increased
difficulties in applying traditional methods to prevent and detect criminal activity.
Banks engaging in electronic banking and electronic money activities can face
legal risks with respect to customer disclosures and privacy protection. Customers who have
not been adequately informed about their rights and obligations may bring suit against a bank.
Failure to provide adequate privacy protection may also subject a bank to regulatory sanctions
in some countries.
Banks choosing to enhance customer service by linking their Internet sites to other
sites also can face legal risks. A hacker may use the linked site to defraud a bank customer,
and the bank could face litigation from the customer.
As electronic commerce expands, banks may seek to play a role in electronic
authentication systems, such as those using digital certificates.7 The role of a certification
authority may expose a bank to legal risk. For example, a bank acting as a certification
authority may be liable for financial losses incurred by parties relying on the certificate. In
addition, legal risk could arise if banks participate in new authentication systems and rights
and obligations are not clearly specified in contractual agreements.
7 A digital certificate issued by a certification authority is intended to ensure that a given digital signature is
in fact generated by a given signer. A bank that undertakes to act as a certification authority could beconsidered to be providing services to clients similar to those associated with providing an account accessdevice or acting as a notary public. A digital signature is a string of data appended to an electronicmessage that is intended to identify uniquely the sender to the recipient. At present, most digital signaturesare generated using a cryptographic algorithm in which the sender uses one mathematical function tocreate the signature and the receiver uses a different, but related mathematical function to verify thesignature. Digital signatures also typically provide a mechanism for verifying the integrity of the message.

2.4. Other risks
Traditional banking risks such as credit risk, liquidity risk, interest rate risk, and
market risk may also arise from electronic banking and electronic money activities, though
their practical consequences may be of a different magnitude for banks and supervisors than
operational, reputational, and legal risks. This may be particularly true for banks that engage
in a variety of banking activities, as compared to banks or bank subsidiaries that specialise in
electronic banking and electronic money activities.
2.4.1 Credit risk is the risk that a counterparty will not settle an obligation for full
value, either when due or at any time thereafter. Banks engaging in electronic banking
activities may extend credit via non-traditional channels, and expand their market beyond
traditional geographic boundaries. Inadequate procedures to determine the creditworthiness of
borrowers applying for credit via remote banking procedures could heighten credit risk for
banks. Banks engaged in electronic bill payment programs may face credit risk if a third party
intermediary fails to carry out its obligations with respect to payment. Banks that purchase
electronic money from an issuer in order to resell it to customers are also exposed to credit
risk in the event the issuer defaults on its obligations to redeem the electronic money.
2.4.2 Liquidity risk is the risk arising from a bank’s inability to meet its
obligations when they come due, without incurring unacceptable losses, although the bank
may ultimately be able to meet its obligations. Liquidity risk may be significant for banks that
specialise in electronic money activities if they are unable to ensure that funds are adequate to
cover redemption and settlement demands at any particular time. In addition, failure to meet
redemption demands in a timely manner could result in legal action against the institution, and
lead to reputational damage.
2.4.3 Interest rate risk refers to the exposure of a bank’s financial condition to
adverse movements in interest rates. Banks specialising in the provision of electronic money
may face significant interest rate risk to the extent adverse movements in interest rates
decrease the value of assets relative to electronic money liabilities outstanding.
2.4.4 Market risk is the risk of losses in on- and off-balance sheet positions
arising from movements in market prices, including foreign exchange rates. Banks accepting
foreign currencies in payment for electronic money are subject to this type of risk.
2.5. Cross border issues
Electronic banking and electronic money activities are based on technology that
by its very nature is designed to extend the geographic reach of banks and customers. Such
market expansion can extend beyond national borders, highlighting certain risks. Although
banks currently face similar types of risks in international banking, it is important to note that
these risks are also relevant to the cross-border conduct of electronic banking and electronic

- 10 -
money. Banks may face different legal and regulatory requirements when they deal with
customers across national borders. For new forms of retail electronic banking, such as Internet
banking, and for electronic money, there may be uncertainties about legal requirements in
some countries. In addition, there may be jurisdictional ambiguities with respect to the
responsibilities of different national authorities. Such considerations may expose banks to
legal risk associated with non-compliance with different national laws and regulations,
including consumer protection laws, record-keeping and reporting requirements, privacy rules,
and money laundering laws.
Operational risk could arise for a bank dealing with a service provider located in
another country, which for that reason may be more difficult to monitor. Banks may also face
other risks as they engage in the provision of electronic banking and electronic money
activities across borders. Banks dealing with foreign-based service providers, or with foreign
participants in electronic banking or electronic money activities, are subject to country risk to
the extent that foreign parties become unable to fulfil their obligations due to economic,
social, or political factors. A bank offering services via open networks like the Internet may be
exposed to credit risk, in that applications for credit from customers in other countries may be
more difficult to evaluate with procedures based upon a more familiar customer base. Banks
accepting foreign currencies in payment for electronic money may be subject to market risk
because of movements in foreign exchange rates.
3. Risk management
For an increasing number of banks there may be a strategic reason for engaging in
electronic banking and electronic money activities. In addition, greater use of electronic
banking and electronic money may increase the efficiency of the banking and payment system,
benefiting consumers and merchants. At the same time, as the preceding discussion indicates,
there are risks for banks engaging in electronic banking and electronic money activities. Risks
must be balanced against benefits; banks must be able to manage and control risks and absorb
any related losses if necessary. Risks from electronic banking and electronic money activities
should also be evaluated in the context of other risks the bank faces. Even though electronic
banking and electronic money activities may represent a relatively small portion of the overall
activities of banks currently, supervisors may still require senior management’s assurance that
critical systems are not threatened by the risk exposures banks take.
The rapid pace of technological innovation is likely to change the nature and
scope of risks banks face in electronic money and electronic banking. Supervisors expect
banks to have processes that enable bank management to respond to current risks, and to
adjust to new risks. A risk management process that includes the three basic elements of
assessing risks, controlling risk exposure, and monitoring risks will help banks and
supervisors attain these goals. Banks may employ such a process when committing to new

- 11 -
electronic banking and electronic money activities, and as they evaluate existing commitments
to these activities.
It is essential that banks have a comprehensive risk management process in place
that is subject to appropriate oversight by the board of directors and senior management. As
new risks in electronic banking and electronic money activities are identified and assessed, the
board and senior management must be kept informed of these changes. Prior to any new
activity being commenced, a comprehensive review should be conducted so that senior
management can ensure that the risk management process is adequate to assess, control and
monitor any risks arising from the proposed new activity.
3.1. Assessing risks
Assessing risks is an ongoing process. It typically involves three steps. First, a
bank may engage in a rigorous analytic process to identify risks and, where possible, to
quantify them. In the event risks cannot be quantified, management may still identify how
potential risks can arise and the steps it has taken to deal with and limit those risks. Bank
management should form a reasonable and defensible judgement of the magnitude of any risk
with respect to both the impact it could have on the bank (including the maximum potential
impact), and the probability that such an event will occur.
A second step in assessing risk is for the board of directors or senior management
to determine the bank’s risk tolerance, based on an assessment of the losses the bank can
afford to sustain in the event a given problem materialises. Finally, management can compare
its risk tolerance with its assessment of the magnitude of a risk to ascertain if the risk
exposure fits within the tolerance limits.
3.2. Managing and controlling risks
Having made an assessment of risks and its risk tolerance, bank management
should take steps to manage and control risks. This phase of a risk management process
includes activities such as implementing security policies and measures, co-ordinating internal
communication, evaluating and upgrading products and services, implementing measures to
ensure that outsourcing risks are controlled and managed, providing disclosures and customer
education, and developing contingency plans. Senior management should ensure that staff
responsible for enforcing risk limits have authority independent from the business unit
undertaking the electronic banking or electronic money activity. Banks increase their ability to
control and manage the various risks inherent in any activity when policies and procedures are
set out in written documentation and made available to all relevant staff.

3.2.1 Security policies and measures
Security is the combination of systems, applications, and internal controls used to
safeguard the integrity, authenticity, and confidentiality of data and operating processes.
Proper security relies on the development and implementation of adequate security policies
and security measures for processes within the bank, and for communication between the
bank and external parties. Security policies and measures can limit the risk of external and
internal attacks on electronic banking and electronic money systems, as well as the
reputational risk arising from security breaches.
A security policy states management’s intentions to support information security
and provides an explanation of the bank’s security organisation. It also establishes guidelines
that define the bank’s security risk tolerance. The policy may define responsibilities for
designing, implementing, and enforcing information security measures, and it may establish
procedures to evaluate policy compliance, enforce disciplinary measures, and report security
violations.
Security measures are combinations of hardware and software tools, and
personnel management, that contribute to building secure systems and operations. Senior
management should regard security as a comprehensive process that is only as strong as the
weakest link in the process. Banks can choose from a variety of security measures to prevent
or mitigate external and internal attacks and misuse of electronic banking and electronic
money. Such measures include, for example, encryption, passwords, firewalls, virus controls,
and employee screening. Encryption is the use of cryptographic algorithms to encode clear
text data into cipher text to prevent unauthorised observation.8 Passwords, pass phrases,
personal identification numbers, hardware-based tokens, and biometrics are techniques for
controlling access and identifying users.
Firewalls are combinations of hardware and software that screen and limit
external access to internal systems connected to open networks such as the Internet. Firewalls
may also separate segments of internal networks using Internet technology (Intranets).
Firewall technology, if properly designed and implemented, can be an effective means of
controlling access and safeguarding data confidentiality and integrity. Because this technology
is complex to design and can be costly, its strength and capabilities should be proportionate
with the sensitivity of the information being protected. A well-planned design should include
enterprise-wide security requirements, clear procedures for operation, separation of duties,
and selection of trusted personnel who are responsible for the configuration and operation of
the firewall.
8 See Security of Electronic Money, Bank for International Settlements, August 1996, especially section
4.1.2 on cryptography, for a detailed discussion of encryption.

Although firewalls screen incoming messages they do not necessarily protect
against virus-infected programs downloaded from the Internet. As a consequence,
management should develop prevention and detection controls to reduce the chance of virus
attack and data destruction, particularly for remote banking. Programmes to mitigate the risk
of a virus infection may include network controls, end-user policies, user training, and virus
detection software.
Not all security threats are external. Electronic banking and electronic money
systems should also be safeguarded, to the extent possible, against unauthorised activities by
current and former employees. As with existing banking activities, background checks for
new employees, temporary employees, and consultants, as well as internal controls and
separation of duties are important precautions to protect system security.
For electronic money, additional security measures may help deter attacks and
misuse, including counterfeiting and money laundering.9 Such measures could include on-line
interaction with the issuer or a central operator; monitoring and tracing individual
transactions; maintenance of cumulative records in a central database; the use of
tamper-resistant devices incorporated into stored-value cards and merchant hardware; and the
use of value limits and expiration dates on stored-value cards.
3.2.2 Internal communication
Aspects of operational, reputational, legal, and other risks can be managed and
controlled if senior management communicates to key staff how the provision of electronic
banking and electronic money is intended to support the overall goals of the bank. At the same
time, technical staff should clearly communicate to senior management how systems are
designed to work, as well as the strengths and weaknesses of systems. Such procedures can
reduce operational risks of poor systems design, including incompatibility of different systems
within a banking organisation; data integrity problems; reputational risk associated with
customer dissatisfaction that systems did not work as expected; and credit and liquidity risk.
To ensure adequate internal communication, all policies and procedures should be
provided in writing. In addition, senior management should adopt a corporate policy of
ongoing education and upgrading of skills and knowledge, consistent with the pace of
technological innovation, in order to limit operational risks arising from lack of staff and
management expertise. Training may include technical course work, as well as time for staff
to keep abreast of important market developments.
9 A detailed discussion of security measures for electronic money can be found in Security of Electronic
Money, Bank for International Settlements, April 1996. That report concluded that a combination ofsecurity measures, rather than reliance on any one particular measure, is likely to be most effective inpreventing and deterring security problems for electronic money.

3.2.3 Evaluating and upgrading
Evaluating products and services before they are introduced on a widespread basis
can also help limit operational and reputational risks. Testing validates that equipment and
systems function properly and produce the desired results. Pilot programs or prototypes can be
helpful in developing new applications. The risk of system slowdowns or disruptions can also
be reduced by policies to review the capabilities of existing hardware and software regularly.
3.2.4 Outsourcing
A growing trend in the industry is for banks to focus strategically on core
competencies and rely on external parties specialising in activities outside the bank’s
expertise. While these arrangements may offer benefits such as cost-reduction and economies
of scale, outsourcing does not relieve the bank of the ultimate responsibility for controlling
risks that affect its operations. Consequently, banks should adopt policies to limit risks arising
from reliance on outside service providers. For example, bank management should monitor
the operational and financial performance of their service providers; ensure that contractual
relations between parties, as well as the expectations and obligations of each party, are clearly
understood and are defined in written, enforceable contracts; and maintain a contingency
arrangement to change service providers in a prompt manner, if necessary.
Security of the bank’s sensitive information is of critical importance. The
outsourcing arrangement may require the bank to share sensitive data with service providers.
Bank management should evaluate the ability of the service provider to maintain the same
level of security as though the activities were conducted in-house, through the review of
service providers’ policies and procedures aimed at protecting sensitive data. Additionally,
supervisors may wish to have the right to independently assess, when necessary, the
competence and the operational and financial performance of the service providers.
3.2.5 Disclosures and customer education
Disclosures and customer education may help a bank limit legal and reputational
risk. Disclosures and programs to educate customers that address how to use new products
and services, fees charged for services and products, and problem and error resolution
procedures can help banks comply with customer protection and privacy laws and regulations.
Disclosures and explanations about the nature of a bank’s relationship to a linked web site
may help reduce legal risk to a bank arising from problems with services or products on the
linked sites.
3.2.6 Contingency planning
A bank can limit the risk of disruptions in internal processes or in service or
product delivery by developing contingency plans that establish its course of action in the

- 15 -
event of a disruption in its provision of electronic banking and electronic money services. The
plan may address data recovery, alternative data-processing capabilities, emergency staffing,
and customer service support. Backup systems should be tested periodically to ensure their
continuing effectiveness. Banks should ensure that their contingency operations are as secure
as their normal production operations.
An important aspect of electronic banking and electronic money is the reliance on
external entities including hardware vendors, software providers, Internet service providers,
and telecommunications companies. Bank management may insist that such service providers
have backup capabilities. In addition, management may consider compensating actions it can
take in the event service providers become impaired. Such plans could include short-term
contracting with other providers, and a policy describing how the bank will address customer
losses associated with the service disruption. Banks should also consider the advisability of
reserving the right to change service providers in a prompt manner if necessary.
Contingency planning may also contribute to limit reputational risk arising from
the bank’s own actions, or from problems experienced by another institution offering the same
or similar electronic banking or electronic money products or services. For example, banks
may wish to establish procedures to address customer problems during system disruptions.
3.3. Monitoring risks
Ongoing monitoring is an important aspect of any risk management process. For
electronic banking and electronic money activities, monitoring is particularly important both
because the nature of the activities are likely to change rapidly as innovations occur, and
because of the reliance of some products on the use of open networks such as the Internet.
Two important elements of monitoring are system testing and auditing.
3.3.1 System testing and surveillance
Testing of systems operations can help detect unusual activity patterns and avert
major system problems, disruptions, and attacks. Penetration testing focuses upon the
identification, isolation, and confirmation of flaws in the design and implementation of
security mechanisms through controlled attempts to penetrate a system outside normal
procedures. Surveillance is a form of monitoring in which software and audit applications are
used to track activity. In contrast to penetration testing, surveillance focuses on monitoring
routine operations, investigating anomalies, and making ongoing judgements regarding the
effectiveness of security by testing adherence to security policies.
3.3.2 Auditing
Auditing (internal and external) provides an important independent control
mechanism for detecting deficiencies and minimising risks in the provision of electronic

- 16 -
banking and electronic money services. The role of an auditor is to ensure that appropriate
standards, policies, and procedures are developed, and that the bank consistently adheres to
them. Audit personnel must have sufficient specialised expertise to perform an accurate
review. An internal auditor should be separate and independent from employees making risk
management decisions. To augment internal audit, management may seek qualified external
auditors, such as computer security consultants or other professionals with relevant expertise,
to provide an independent assessment of the electronic banking or electronic money activity.
3.4. Management of cross border risks
Cross border risks may be more complex than risks banks face within their home
country. Hence, banks and supervisors may need to devote added attention to assessing,
controlling, and monitoring operational, reputational, legal and other risks arising from cross
border electronic banking and electronic money activities.
Banks that choose to provide services to customers in different national markets
will need to understand different national legal requirements, and develop an appreciation for
national differences in customer expectations and knowledge of products and services. In
addition, senior management should ensure that existing systems for credit extension and
liquidity management take into account potential difficulties arising from cross border
activities. A bank may need to assess country risk and develop contingency plans that take
into account service disruptions due to problems in the economic or political climate abroad.
A bank may also face difficulties in enforcing the fulfilment of a foreign service provider’s
obligations. In the case of banks relying on service providers located abroad, national
supervisors may want to assess the accessibility of information from, and consider the
activities of, cross-border service providers on a case-by-case basis.
National supervisors can play an important role by identifying and discussing
jurisdictional ambiguities. They can also continue efforts to develop measures to detect unsafe
and illegal practices. Finally, national supervisors can continue, and strengthen, cooperative
efforts to share information about product and service innovations and industry practices.
